Short answer: the Kali Audio LP-6 V2. It ranks #17 of 40 powered bookshelf speakers by sound quality at $398; the JBL 4329P ranks #19 and costs $4500, so there is not much of a tradeoff to weigh.
On the Kali Audio LP-6 V2 side: Outstandingly neutral active monitor for the money, with no audible amplifier hiss in Erin’s listening and excellent horizontal directivity from the contoured waveguide. Set against that: A vertical directivity disturbance around 1.5-2kHz makes ear height important; desk or console reflections and ceiling bounce can expose the crossover lobing, so absorption may help.
The case for the JBL 4329P: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement. The tradeoff: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC.
Buy the Kali Audio LP-6 V2. It ranks higher for sound quality than the JBL 4329P and costs less, so there is no real case for the other one.

Kali Audio LP-6 V2: $398/pair Amazon Sweetwater
Pros: Outstandingly neutral active monitor for the money, with no audible amplifier hiss in Erin’s listening and excellent horizontal directivity from the contoured waveguide. Erin measured 42Hz F3 and on-axis linearity within approximately -2.51/+1.99dB. The pair remains respectably linear to roughly 102dB at 1m, the front port controls turbulence, and rear DIP switches provide practical boundary-placement profiles plus LF/HF trims. Balanced XLR/TRS and unbalanced RCA inputs broaden compatibility; Erin needed only about +1.5dB near 8kHz for his preferred amount of air.
Cons: A vertical directivity disturbance around 1.5-2kHz makes ear height important; desk or console reflections and ceiling bounce can expose the crossover lobing, so absorption may help. Limiting becomes visible above 96dB/1m, and from 76 to 96dB the low-frequency/midband balance drops by roughly 1dB, making this better as a nearfield or modest-distance monitor than a far-field high-output system. There is no digital input or network control, and each speaker needs AC power and a separate signal cable.

JBL 4329P: $4,500 Amazon
Pros: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement, with strong bass authority rather than a rolled-off, thin low end. Wide, constant horizontal directivity through the midrange and into the treble (about ±60°, wider than most horn-loaded designs which tend to run closer to ±40°) gives a wide, stable stereo image without needing to toe the speakers out and lose top-end energy. The reviewer listened for an hour-long sessions repeatedly without listener fatigue, across two very different rooms, with consistently great results in both. Extensive connectivity: USB, Optical, Bluetooth, analog, 3.5mm, AirPlay 2, and 24-bit/192kHz support; comes with a remote.
Cons: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC. The supplied ethernet link cable between the two speakers is short - workable at close range but not long enough for wider speaker placement, so budget for a longer aftermarket cable if your setup needs it. A dip around 900Hz shows up in the on-axis measurement that the reviewer couldn’t fully explain (ruled out the ports as the cause, suspects cabinet edge diffraction), though it wasn’t something that bothered him in listening. At $4,500/pair, this is a serious investment for a bookshelf-format speaker.
